Specicaton of Letters Patent.

Patented Oct. 4, 1910.

Application filed May 14, 1910. -Serial No. 561,359.

To all lwhom 'ii 'may concern:

Be it known that I, ABBoT A. Low, a citizen of the lUnited States, and resident of Horseshoe, St. Lawrence county, New York,

have invented certain new and useful Imrovements in Economizers, of which the following is a specification.

This invention relates to internal combustion engines, and more particularly to lo what are known as oil engines.

The object of the invention is to provide improved means for vaporizing the oil, whereby the vaporization is much more thorough than heretofore, thus avoiding waste of fuel.

To this end the invention consists in the constructions, arrangements and combinations hereinafter described, illustrated in fitting embodiments in the accompanying 2O drawings, and more particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a view partly in vertical section and partly in elevation showing the head of an engine cylinder and the passage leading to the intake with my improvements embodied therein; Fig. 2 is a plan view of the same parts, partly in horizontal sect-ion.

Referring now to these views, the numeral 10 indicates the head of an engine cylinder,

11 the intake valve thereof, and 12 the passage or conduit leading to the intake. In this passage is located a vaporizing coil 13, having the terminals 14 whereby the coil may be supplied with electric current from any suitable source. Over this coil is an economizing chamber 15, forming an im portant` part of my invention. The function of this chamber is to receive the oil and to distribute it over the vaporizing coil,

whereby much better results are obtained lthan when the stream or supply of oil is directed immediately against the coil. The structure of this economizing chamber may be widely varied. Preferably, it is substantially horizontal, with its rear portion upward inclined, so that oil will notl collect in this end. In the particular construction illustrated, the econoinizing chamber is in the nature of a tube or pipe, provided below with a longitudinal series of perforations 16; but the chamber may be of any suitable form or shape, and there may be a plurality of rows of perforations. As shown, the

chamber is comparatively shallow. The perforations should be comparatively line, so

as to divide the oil into small streams or drops before reaching the vaporizing coil. A shoulder 152L is provided at the open end of the economizer 15 to prevent the escape of the oil.

The economizing chamber 15 may be supplied in a variety of ways. I have shown two converging, horizontal nozzles 17, which are spaced considerably in front of the open front end of the chamber 15 and which deliver streams of oil thereto, under pressure or otherwise. Instead of being spaced from the chamber 15, the nozzles 17 may be connected directly with the chamber. I have also shown an oil cup- 18 over the chamber 15 and connected with the rear part thereof by a vertical pipe 19. This cup may be used to furnish an auxiliary, regulable supply of oil to the chamber 15 and provides a convenient means for supplying a richer miX- ture of gas for priming and starting.

A suitable regulating valve, 20, for controlling the flow of oil in the pipe 19, may be operated in a variety of ways. I have shown it as being provided with a shaft 21 on which is a worm gear 22, that is meshed by a worm 28. On the shaft of the worm is `a handle crank 24. Associated with this handle crank is a locking pin 25, which may be conveniently released by the same hand that grasps and operates the handle 24C. This pin engages a stationary locking member 2G, which may be, as shown, in the nature of a disk provided with a circular series of holes in which the pin is received. Thus, the valve may be locked at various degrees of opening. If the engine have a plurality of cylinders, each provided with a cup 18 and a valve 20, the several valves may be provided with cranks 27, connected by a bar or link 28, so that by means of a single mechanism, comprising the parts 22, 23, 211, 25, and 2G, all the valves may be operated or locked simultaneously.

The valve 11 of the engine may be operated in any suitable way. It will be under stood that air is taken in through the air pipe 12a.

By means of the economizing chamber forming part of this invention, a material economy of fuel. is effected. The oil is con fined where vaporized, instead of being permitted to spray indiscriminately about the passage leading to the intake. The engine will start more readily, because the Vaporizing 1s effectively performed from the beg1nning. Also, better results are obtained when ruiming at slow speed than is possible when the oil is directed immediately against the vaporizing coil.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is:

l. An economizer adapted for use in an oil engine, comprising a horizontal tubular member provided with an opening at one end through which the fluid may be injected and with a raised portion below :aid opening to prevent the li'tfrd from liowing back and also provided with perforations in the lower wall thereof to permit the fluid to be delivered to the vaporizer of the engine.

2. An economizer adapted for use in an oil engine, comprising a horizontal tubular member provided with an opening at one end through which the fluid may be injected and with an upwardly inclined portion at the opposite end and also provided with perforations in the lower horizontal wall thereof to permit the fluid to be delivered to the vaporizer of the engine.

3. An economizer adapted for use in an oil engine, comprising a horizontal tubular member provided with an opening at one end through which the fluid may be injected and with a raised portion below said opening to prevent the fluid from flowing back, said tubular member being also provided at the kend opposite said opening with an upwardly inclined portion and with perforations in the lower horizontal wall between said raised portion and said inclined portion to permit the fluid to be delivered to the vaporizer of the engine.

4L. An economizer adapted for use in an oil engine, comprising a horizontal tubular member having one end thereof formed to permit the fluid to be injected and also provided with perforations in the lower horizontal wall thereof, said member being also provided at one end with an upwardly in clined portion, and an auxiliary oil reservoir connected with said inclined portion.

5. In an oil engine, the combination of a passage leading to the intake, a vaporizing coil therein, a shallow, substantially horizontal economizing chamber over said coil and provided beneath with perforations adapted to distribute the oil over said coil, and means for delivering oil substantially horizontally into said chamber.

6. In an oil engine, the combination of a passage leading to the intake, a vaporizing coil therein, an economizing chamber over said coil having a substantially horizontal. bottom with its rear portion inclined upward, the bottom of said chamber being pierforated so as to distribute the oil over said coil, and means for delivering oil into the forward part of said chamber toward the rear thereof.

7. In an oil engine, the combination of a passage leading to the intake, a vaporizing coil therein, an economizing chamber over said coil and provided beneath with perforations adapted to distribute the oil over the coil, a nozzle arranged horizontally to direct a stream of oil into said chamber, and a valved oil cup over said chamber and connected therewith.
